How to fix a non working Internet Connection

My Desktop computer does not detect my internet connection. Running the troubleshooter, it reports Windows could not automatically detect this network's proxy settings. There might be a problem with the WiFi adapter. My WiFi modem is connected and working as it should, as I am using the internet to write this article from my wife's laptop computer.

What do I do next? Please advise.

Many thanks.

Tony

    Hi, thank you for replying. By default, some services are stopped if they're not in use and will automatically start when you use the particular app for that service. If the PC takes time to start up, I recommend enabling each app in Startup apps and observing the device, as long as it will not cause the internet to stop again.

    Or another option is to enable each service to check what is causing the issue and uninstall the app that is causing the problem.

    Hi Bernard, Thank you so much for your knowledgeable and extended sets of possible solutions to my problem. The first method to roll back the Network driver did not work. Then I carried on with the Command Prompts, and the last three "ipconfig" were not recognised by the system. The last clean Boot option did finally work, and I now have my Internet connection back. I have to tell you that when I opened the System Config. I found most of the services had been stopped, but by whom or what? I am the only user of this computer, and I have not made any changes there. Anyway, I hid all Microsoft services, but the remaining non Microsoft ones are all enabled, should I live them like that? And lastly, in Selective Start, I have the System services and Start up items ticked. The computer takes its time to start up from scratch, do you think this is the best setting? And just to thank you once again for your time and clear explanations of what to do. I am extremely grateful and send you my very best wishes.

    Tony

    Hi, I'm Bernard, a fellow Windows user. I'm happy to help!

    I understand the issue you have. There is nothing to worry about. I am here to assist. Based on your inputs, it seems that there is an incompatibility with the network driver. Moreover, kindly follow the steps below for us to sort out the issue:

    Method 1. Roll back the Network driver:

    -Press the Windows key + X

    -Go to Device Manager

    -Expand the Network Adapters

    -Look for the Wireless driver that was installed

    -Right-click and click Update Driver

    -Select Browse my computer for drivers

    -Click Let me pick from a list of available drivers on my computer

    -Choose an old driver or another driver name of driver then select it and hit next until it installs.

    If the issue persists, run the following command in Command Prompt (Admin). Follow the steps below to do so.

    These sets of commands will reset the internet connection and recalibrate the internet settings you have.

    Press Windows Key + X.

    Click on the Terminal (Admin) or Windows PowerShell (admin)

    Type the following commands, and hit Enter after each command:

    netsh int tcp set heuristics disabled
    netsh int tcp set global autotuninglevel=disabled
    netsh int tcp set global rss=enabled
    netsh winsock reset
    netsh int ip reset
    ipconfig /release
    ipconfig /renew
    ipconfig /flushdns
    

    If the same issue follows the methods below:

    Do a clean boot:

    A “clean boot” starts Windows with a minimal set of drivers and startup programs so that you can determine whether a background program is interfering with your game or program.

    • In the search box on the taskbar, type msconfig and select System Configuration from the results.
    • On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
    • On the Startup tab of System Configuration, select Open Task Manager.
    • Under Startup in Task Manager, for each startup item, select the item and then select Disable.
    • Close Task Manager.
    • On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.
